What is the relationship between laser frequency and wavelength of automatic laser pcb cutting machine?
Relationship between wavelength and frequency? What is the formula for wavelength?
The relationship between the wavelength and frequency of the
laser PCB cutting machine is inversely proportional. The specific formula depends on what wave transmits in what transmission medium. For example, the wavelength of light = light speed * (1 / frequency) the unit of light speed is meters per second, and the spectra of different colors have different frequencies
Laser wavelength and frequency of
laser PCB cutting machine:
The center frequency of different lasers is different, and the center frequency of some lasers can be adjusted.
In short, there are red laser and green laser, and some lasers can be adjusted from red laser to green laser.
However, there is no laser with both red and green light. A laser has only one central frequency
The laser frequency range is 3.846 * 10 ^ (14) Hz to 7.895 * 10 ^ (14) Hz
Wavelength = 3 * 10 ^ 8 / frequency
What is the relationship between brightness, power and wavelength of
laser PCB cutting machine:
1. In essence, laser intensity has nothing to do with wavelength
2. But in fact, the laser intensity is related to the wavelength.
The sensitivity of human eyes is different with different colors of laser. Even if the laser intensity is the same, the brightness felt by human eyes is also different.
The ability of different colors of laser to pass through the atmosphere is different, that is, the attenuation is different. Even if the laser intensity is the same, the brightness felt by human eyes is also different
Laser brightness is a comprehensive subjective feeling or description of laser wavelength and laser power. There is a wavelength meter for measuring laser wavelength and a power meter for measuring laser power. There are objective standards and calibrated general instruments and equipment for measuring these two physical quantities. Key words for measuring laser brightness: laser brightness, laser power, wavelength, relationship.
What does the wavelength mean?
Laser wavelength refers to the output wavelength of laser and is an important parameter of laser beam output. The corresponding output frequency is called laser frequency.
Laser is a special kind of light, which has the characteristics of light, but it has purer color and greater energy than ordinary light. The wavelength of laser is the same as that of ordinary light. Laser exists from infrared to ultraviolet. The wavelength is about the order of thousands of nanometers or less. The closer to the ultraviolet region, the shorter the laser wavelength, which can be hundreds of nanometers or even smaller.
The characteristics of this frequency output of the laser are completely determined by the properties of the transition luminescence between the relevant energy levels of the atoms (or molecules and ions) that make up the laser working material, as well as the structure and properties of the resonant cavity.
